SEAL-TRAP FOR WATER-CLOSETS, SEWERS, 84.0.

SPECIFICATION forming part of Letters Patent No. 241,568, dated May 17, 1881.

' Application filed December 21, 1880. (ModeL) To all whom it may concern Be it known that I, ORLANDO W. SPRATT, a citizen of the United States, residing in the city and. county of Philadelphia, and State of 5 Pennsylvania, have invented a new and useful Improvement in SealTraps for Water-Closets, Sewers, 850., which improvement is fully set forth in the following specification and accompanying drawings, in which.

Figure 1 is a top or plan view of the interior of the trap embodying my invention. Fig. 2 is a vertical section thereof, partly open. Fig. 3 is a vertical section thereof in line a: m, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in imparting vertical and lateral motions to the flanged cap or valve of a seal-trap for water-closets, 850., provided z with a guttered seat for said cap or valve, whereby the cap may be quickly opened and removed to permit the uninterrupted passage of matters through the trap, and likewise quickly closed and sealed, so that the escape of noxious vapors is reliably prevented, the opening and closing motions being each ac complished by the single operation of a shaft or red.

Referring to the drawings, A represents a chamber adapted to be located beneath a water-closet bowl, sink, sewer-inlet, &c., or other place requiring a seal-trap, said chamber having an inlet, a, and a discharge or outlet, 1), which leads to the cesspool, sewer, &c. The portion of the base which surrounds the top of the wall of the opening a is sunken, forming a groove or gutter, c, for the reception of mercury or other sealing medium.

B represents a cap or valve, which is formed with a (lownwardlyprojecting rim, (1, which, when the trap is closed, dipsinto the mercury in the gutter c as the seat of the valve. To said valve is pivoted a lever, G, which, at the opposite end, is formed with a-spherical head, D, adjacent thereto, a ball, E, and between the ball and pivot a bearing part, F.

The chamber A has a lateral extension or offset, Gr, and on the upper and lower walls thereof are projections H with concave faces for the reception of the ball E, forming together a ball-and-socket joint, and likewise projecting ribs J, between which the bearing part F is guided, and on which itmoves.

K represents a transversely-extending rod or shaft mounted on the extension G, and having on the portion within the same a spirallygrooved collar or piece, L, the groove thereof receiving the spherical head D of the lever O.

The shaft K is provided with a crank or other mechanism operated by hand, or connected to the lid of the water-closet, 850., so that the opening and closing of said lid will rotate the shaft in opposite directions.

In Fig. 1 the trap is closed and the parts are in their normal position. 5

When service is required of the water-closet, 850., the shaft K is rotated. The action of the spiral collar L on the head D of the lever C I imparts downward and lateral motions to the end of the lever having said head, whereby the valve B is lifted from the gutter c and moved to the unoccupied portion A of the chamber A, whereby the dischargeopening bis uncovered, and the inlet a and said opening b are in communication, so that matters from the water closet, sewer-inlet, 850., may pass out without interruption. The rotation of the shaft K in reverse direction returns the valve B over the disch arge-openin g I) and lowers it to its full extent, so that the rim (1 dips into the mercury, 850., of the gutter c, the lever O dropping into the notch J of the bottom projection, J, and thus the trap is reliably and serviceably sealed.

1 am aware that it is not new to operate a waste-pipe valve so that it receives vertical and lateral motions to open and close the same; but this is accomplished first by a rotary motion of a shaft and next by a lifting motion thereof, two distinct motions, wherefore I dis claim such features. 0

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A seal-trap for water-closets, 850., having a flanged valve and a guttered seat, a longitudinally-extending lever connected to the valve, and a transversely-extendin g shaft provided with a lifting and shifting device, substantially as described, whereby by a single motion of the shaft the flange of the valve is raised clear of the guttered seat and the valve L, and rotary shaft K, substantially as and for is moved laterally, and on the opposite single the purpose set forth. motion of the shaft the valve is returned and T dipped into the guttered seat, for the purpose ORLANDO S1 RATT' 5 set forth.
